Description

Technical Field

[0001] This utility model relates to the field of metal contact technology, specifically a U-shaped metal contact. Background Technology

[0002] Metal contacts are special designs used to control the opening and closing of circuits. They conduct or disconnect electricity through metal contacts. Metal contacts are mainly made of metal materials, with common materials including silver-nickel alloys, silver-cadmium alloys, and pure silver. The choice of these materials depends on the specific application and performance requirements. For example, silver-nickel alloys are often used as ideal contact materials due to their good conductivity and hardness.

[0003] In current metal contacts, the metal sheet makes contact with the contact body by sliding or flipping. However, during the sliding or flipping process, there will be a certain degree of shaking or misalignment. After a long period of use, the metal sheet will develop a large misalignment due to long-term sliding or flipping, and will gradually become unable to make contact with the contact, resulting in functional failure. Summary of the Invention

[0004] The purpose of this utility model is to provide a U-shaped metal contact whose flip base can accurately contact the protective plate each time it is flipped, so that the metal contact will not be misaligned after long-term use, which helps to extend its service life.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A U-shaped metal contact, comprising a mounting plate, a contact mechanism disposed on the mounting plate, and a conducting mechanism located on one side of the contact mechanism. The contact mechanism includes a protective plate and a contact body disposed on the protective plate, and the contact mechanism is U-shaped. A groove is formed on the end face of the protective plate away from the mounting plate. A spring and a sliding block connected to the spring are disposed in the groove. A matching groove is formed on the end face of the sliding block away from the spring. The conducting mechanism includes a torsion spring, a flip seat disposed on the torsion spring, and a metal guide plate disposed on the flip seat. An extension strip is fixedly connected to the flip seat. A positioning protrusion is provided on the extension strip. The end of the positioning protrusion away from the extension strip is adapted to the matching groove on the sliding block, so that the extension strip and the flip seat can be positioned after the positioning protrusion is engaged in the matching groove, thereby ensuring the accurate position of the metal guide plate each time it is used.

[0006] Preferably, there are two grooves, and the two grooves are symmetrical about the two ends of the protective plate; so that the two grooves can correspond to the two positioning protrusions respectively.

[0007] Preferably, the end of the spring away from the sliding block is connected to the inner wall of the groove; this allows the spring to exert its elastic effect, causing the sliding block to extend and retract within a certain range, thereby engaging with the positioning protrusion and fixing the positioning protrusion.

[0008] Preferably, the conducting mechanism further includes two positioning bases, which are respectively installed at both ends of the torsion spring; this ensures that the structure of the torsion spring remains stable and that it can work normally.

[0009] Preferably, the metal conductor is in contact with the contact body to achieve a circuit.

[0010] Preferably, the extension bar is L-shaped, and there are two extension bars, which are symmetrical about the two ends of the flip base.

[0011] Preferably, an angle is formed between the positioning protrusion and the extension strip, and the value of the angle is between 70° and 85°.

[0012] Preferably, a raised ring is provided on the outer side of the positioning protrusion, and the raised ring is adapted to the matching groove.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: By setting the contact mechanism as a U-shape, when the flipping seat flips with the torsion spring, it can drive the two positioning protrusions and two protruding rings on it to extend into the two grooves and cooperate with the two sliding blocks respectively. After the positioning protrusions and sliding blocks are combined and positioned, the flipping seat and the metal guide plate can be positioned, so that the flipping seat can accurately contact the protective plate every time it flips, so that the metal contact will not be misaligned after long-term use, which is conducive to extending its service life.

[0023] Please see Figure 1 The present invention provides an embodiment of a U-shaped metal contact, comprising a mounting plate 1, a contact mechanism 2 disposed on the mounting plate 1, and a conducting mechanism 3 located on one side of the contact mechanism 2;

[0024] Please see Figures 2 to 3The contact mechanism 2 includes a protective plate 21 and a contact body 22 disposed on the protective plate 21. The contact mechanism 2 has a U-shaped design. A groove 23 is formed on the end face of the protective plate 21 away from the mounting plate 1. There are two grooves 23. The grooves 23 are not horizontal, but have a certain inclination angle. The two grooves 23 are symmetrical to the two ends of the protective plate 21. The conduction mechanism 3 includes a torsion spring 32, a flip seat 33 disposed on the torsion spring 32, and a metal guide plate 34 disposed on the flip seat 33. The conduction mechanism 3 also includes two positioning bases 31. The two positioning bases 31 are respectively installed at the two ends of the torsion spring 32, so that the structure of the torsion spring 32 remains stable and can work normally. The metal guide plate 34 is in contact with the contact body 22 to realize the passage. An extension strip 35 is fixedly connected to the flip seat 33. The extension strip 35 has an L-shaped design. There are two extension strips 35. The two extension strips 35 are symmetrical to the two ends of the flip seat 33. The extension strip 35 is provided with positioning protrusions 36.

[0025] Please see Figures 4 to 5 A spring 24 and a sliding block 25 connected to the spring 24 are provided in the groove 23. The end of the spring 24 away from the sliding block 25 is connected to the inner wall of the groove 23, so that the spring 24 can exert its elastic effect and drive the sliding block 25 to extend and retract within a certain range. A matching groove is formed on the end face of the sliding block 25 away from the spring 24. The end of the positioning protrusion 36 away from the extension strip 35 is adapted to the matching groove on the sliding block 25, so that the positioning protrusion 36 can be positioned after it is inserted into the matching groove, thus ensuring the accurate position of the metal guide plate 34 each time it is used. An angle is formed between the positioning protrusion 36 and the extension strip 35, the value of which is between 70° and 85°. A protruding ring 37 is provided on the outside of the positioning protrusion 36. The protruding ring 37 is adapted to the matching groove. The outer diameter of the protruding ring 37 is larger than the outer diameter of the positioning protrusion 36, so it can be more tightly adapted to the matching groove, thus fixing the positioning protrusion 36.

[0026] In operation, the flip seat 33 is pushed, causing it to flip along with the torsion spring 32, which in turn drives the metal guide plate 34 on it to engage with the contact body 22, thus establishing a passage. During the passage process, the two extension strips 35 also flip, causing the two positioning protrusions 36 to enter the two grooves 23. Finally, the two positioning protrusions 36 engage and fix with the matching grooves of the two sliding blocks 25, thus determining the position of the flip seat 33. Therefore, the accuracy of its position is ensured every time the flip seat 33 is used, which helps to extend its service life.

[0027] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
